Original score/soundtrack

Just bought Pandora’s Box and I must say I am impressed with the film, although I’m not sure I loved the film. The supplements disc also seems to be very well put together, as usual.
One curiosity about the original audio soundtrack, I am wondering if the original soundtrack was recorded separately from the film. From what I’ve read, the original soundtrack has been lost. I am interested to learn more about this lost original soundtrack. I listened to the Cabaret-style score on the dvd, It seemed to suit the mood the best.

I’d like to know more about the four scores on the Criterion release. who are they by and what are they like?

I’ve only listened to the modern classical score by Peer Raben — it’s excellent.

Just purchased Pandora’s Box – am anxious to screen it. I love the packaging!
